Important Safety Precautions
Connector
Metal sleeve
Prior to shipment from the factory, JVC products are strictly inspected to conform with the recognized product safety and electrical codes
of the countries in which they are to be sold. However, in order to maintain such compliance, it is equally important to implement the
following precautions when a set is being serviced.
v
Precautions during Servicing
1. Locations requiring special caution are denoted by labels and
inscriptions on the cabinet, chassis and certain parts of the
product. When performing service, be sure to read and comply with these and other cautionary notices appearing in the
operation and service manuals.
2. Parts identified by the
such as fuses and circuit protectors are critical for safety.
Replace only with specified part numbers.
3. Fuse replacement caution notice.
Caution for continued protection against fire hazard.
Replace only with same type and rated fuse(s) as specified.
4. Use specified internal wiring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
5. Use specified insulating materials for hazardous live parts.
Note especially:
1) Insulation Tape 3) Spacers 5) Barrier
2) PVC tubing 4) Insulation sheets for transistors
6. When replacing AC primary side components (transformers,
power cords, noise blocking capacitors, etc.) wrap ends of
wires securely about the terminals before soldering.
symbol and shaded ( ) parts
12. Crimp type wire connector
In such cases as when replacing the power transformer in sets
where the connections between the power cord and power
transformer primary lead wires are performed using crimp type
connectors, if replacing the connectors is unavoidable, in order to prevent safety hazards, perform carefully and precisely
according to the following steps.
1) Connector part number : E03830-001
2) Required tool : Connector crimping tool of the proper type
which will not damage insulated parts.
3) Replacement procedure
(1) Remove the old connector by cutting the wires at a point
close to the connector.
Important : Do not reuse a connector (discard it).
cut close to connector
Fig.3
(2) Strip about 15 mm of the insulation from the ends of
the wires. If the wires are stranded, twist the strands to
avoid frayed conductors.
15 mm
Fig.1
7. Observe that wires do not contact heat producing parts
(heatsinks, oxide metal film resistors, fusible resistors, etc.)
8. Check that replaced wires do not contact sharp edged or
pointed parts.
9. When a power cord has been replaced, check that 10-15 kg of
force in any direction will not loosen it.
Power cord
Fig.2
10. Also check areas surrounding repaired locations.
11. Products using cathode ray tubes (CRTs)
In regard to such products, the cathode ray tubes themselves,
the high voltage circuits, and related circuits are specified for
compliance with recognized codes pertaining to X-ray emission.
Consequently, when servicing these products, replace the cathode ray tubes and other parts with only the specified parts.
Under no circumstances attempt to modify these circuits.
Unauthorized modification can increase the high voltage value
and cause X-ray emission from the cathode ray tube.

PRECAUTIONS FOR SERVICING
1.1 BEFORE DISASSEMBLING AND REASSEMBLING
1.1.1 Precautions
1. When disconnecting and reconnecting connectors, pay careful attention to their wirings not to damage them, particularly
to the wiring of the CCU’s camera connector that requires
the most meticulous care for disconnection and connection.
2. When unsoldering chip parts (IC in particular) for replacement, completely remove solder particles from them and their
surroundings beforehand. Moreover, pay heed to the circuit
pattern not to exfoliate it from the substrate during replacement of a chip part.
3. Don’t use any chip part that was once removed.
4. Handle the optical block assembly with meticulous care.
Don’t apply it a strong shock.
5. There is a lithium battery for backing up the timer on the
POWER board assembly. Pay careful attention to the lithium
battery for accident prevention.
1.1.2 Disassembly of optical block assembly
Since the CCD is precisely glued to the prism in the optical
block assembly, the CCD cannot be replaced individually if
it comes into failure. Therefore, the optical block assembly
is subject to repair by the JVC Home AV Network Business
Unit. If there is something wrong in the optical block assembly, send the camera head assembly whole with a written
request filled out with necessary matters to the Service Engineering Section, Home AV Network Business Unit, JVC.
1.2.2 Tools and jigs required for repair and adjustment
Use the following tools, jigs and test instruments to perform
check and adjustment properly.

Warnings for accident prevention in handling battery
WARNING: Fire, Explosion, Leakage and Burn Hazard. Do not recharge, Disassemble, Heat Above
212°F , Incinerate, Or Expose Contents T o Water. Be Sure The Battery Is Inserted In The Right Direction.
The lithium battery incorporates inflammable substances such as lithium and organic solvent, etc.
inside.
If the lithium battery is handled in a wrong way, it may cause injury, fire and other dangerous
accident caused by heating, bursting, firing, etc. Be sure to follow the instructions mentioned below
to prevent you from an unexpected accident before unpacking, in and after using the battery.
1. Be careful of short-circuit.
If the positive (+) and negative (-) terminals come into contact with each other or with other metallic
material, the battery is shortcircuited. If many batteries are left disorderly and their terminals are in contact
with others, some of the batteries may generate heat, burst or fire and resultingly cause accident.
2. Neither immerse battery in water nor throw it into fire.
If the lithium battery is immersed in water or thrown into fire, it may fire or burst violently.
3. Avoid heating the battery.
If the lithium battery is heated at a temperature of 100°C or more, the electrolyte may leak from the battery
because the plastic materials such as gasket and separator are damaged or the battery may burst or fire
because the battery is heated by internal shortcircuit.
4. Avoid directly soldering the battery.
If the lithium battery is directly soldered, the electrolyte may leak from it because the plastic materials such
as the gasket and separator are damaged or the battery may burst or fire because it is heated by internal
shortcircuit.
5. Avoid charging the battery.
If the primary battery is charged, the battery may generate gas inside and it may resultingly cause
expansion, burst or fire of the battery.
6. Avoid dismantling the battery.
If the lithium battery is dismantled, some kind of gas is generated and it stimulates the throat or the
dismantled battery may fire because the negative lithium reacts on water and generates heat.
7. Avoid deformation with pressure.
If the lithium battery is deformed with pressure, the electrolyte may leak from it because of warp or
damage in the sealing, or the battery may burst or fire because it is heated by internal shortcircuit.
8. Don’t use batteries of different types or old ones mixedly.
If batteries of different brands/types are mixedly used or new and old batteries are mixedly used, it may
cause expansion, burst or fire of the batteries because they are over-discharged by difference in their
characteristics of voltage, capacitance, etc.
9. Avoid setting of the battery in wrong polarities.
If the battery is set in wrong polarities (+ and - poles are set reversely), the battery may be shortcircuited
and it may resultingly cause heating, bursting or firing in the battery.

SECTION 3
INSTALLATION MANUAL
For installing and operating the system which this camera is incorporated in, be sure to follow the instructions
mentioned below.
1. Use the AA-V31U isolation transformer to supply the power to every unit of the system.
2. Ground the AA-V31U. (Please refer to “4. Check of grounding (AA-V31U)”)
3. Cover disused power outlets of the AA-V31U with protection brackets respectively.
1. Safety precautions
• Before starting installation, carefully read “Safety precautions” appearing on pages 4 to 8 of the instructions.
2. Connection of system components
• Connect each unit referring to “Connection” appearing on page 9 of the instructions.
• Please install isolation transformer near the equipotential terminal of video cart.
• When installing the system, power supply cords should be routed so that they are not pinched by items placed upon
or against them. Besides that, when moving the system, please pay special attention to power cords as the cart will
not be fallen down.
Please do not connect other equipment to the signal in - or outputs during use of the system at the patient - unless
you are using facility for galvanic separation, e.g. electro-optical transimitter.
The system may not be changed without additional checking of the safety provisions of EN 60601-1-1. Please note
that the party (person or company) which is assembling, installing or modifying a medical sytstem is responsible that
it complies with all relevant requirements of that standard.
3. Connection of each unit to the power supply unit
• Connect the power cable of each unit to the isolation transformer (AA-V31U) referring to the following figure.
The plug of each power cable must be fastened by a band and a holder, which needs to be fastened with a screwdriver.
Washer
Use exclusive screws to fasten
the plug and tighten the screws
with the special screwdriver.
(Pay need to the orientation of
each screw.)
Cover disused power outlets of the
AA-V31U with exclusive protection
brackets,
and fasten each protection bracket
with exclusive screws that need the
special screwdriver for tightening.
When fastening the band to the AA-V31U with an exclusive screw, be sure to put two washers (two different
types) on the screw so that they are inserted between the band and the AA-V31U.
• When fitting the cover to the DZ-VCA3U for medical use, be sure to disconnect the power cord from the AC outlet in
the hospital/clinic to avoid getting an electric shock.
• Be careful not to insert a screwdriver or the like into the AC outlet.
